The UCD3138 is optimized for AC/DC and isolated DC/DC conversion. Its peripheral set allows it to control multiple power stages simultaneously.
The UCD3138 is a 32-bit digital power controller based on the ARM7TDMI-S core. It distinguishes itself from general-purpose DSPs (like the TI C2000 series) by integrating highly specific hardware peripherals designed to execute Pulse Width Modulation (PWM) and Proportional-Integral-Derivative (PID) control loops without significant CPU intervention. This architecture allows for deterministic, high-frequency control required in server power supplies, telecom rectifiers, and industrial power systems.
